The rocker arm R which is pivo'tally supported upon the sliding member79 is associated with adjustable means which controls the length of thestroke of the reciprocating is secured to the rocker arm R through themedium of this adjustable'means various lengths of coils may be wound,as will now be described. The rectangular plates 70 and 71 which form.the rocker arm R are vided with depending members 166 and 167 which,Whenthe plates 70 and 71 are secured together, form a depending leg 168,which is provided with a slot 169.

A rack 170 which rests in a suitable channel 171 in the housing C isprovided with teeth 172 out in its side face 173 and is secured to astud 174 intermediate of its ends by means of a riveting operation orany other suitable means. The forward end 175 of the stud 174 is 4threaded and protrudes I through a slot 176 in the housing 0 and isadapted to receive a knob 177 and a collar 178 provided with a centralorifice is adapted to be slipped over this protruding end 175 of thestud 174 and rests between the knob 17 7 and the housing C. The housingC is provided with a channel 179 which is adapted to receive therectangular shaped portion 180 of the collar 17 8 to permit the collar178 to slide up and down inlthe channel 179. The knob 177 and collar 178are used for clamping purposes. A bushing 181 provided with fiat faces182 rests in the slot 169 in the depending leg 168 of the rocker arm Rand is adapted to slide in the said slot 169. The portion 1830f the stud174. extends through a central orifice 185 in the bushing 181 and thereduced end 186 of the stud 174 Which protrudes, is threaded to receivea nut 187, a suitable washer 188 being placed between the nut 187 andthe face of the depending leg 168 of the rocker arm R. The

throu hthe-bushing 181 is slightlylonger than t e bushing 181, so thatwhen the nut 187 is turned down, the washer 188 will be; locked but atthe same time allow the bushing 181to rock on' the stud 174 and permitthe bushing 181 to slide in the slot 169. The knob 177 which is threadedupon the forwardend 175 of the stud 174 which protrudes throu h the slot176 in the housing 0 is provided with a handle 189 which facilitatesturning of the knob 177. I The toothed rack 170 meshes with a pinion190integrally formed with a rod 191 which extends through an 'orifice192 in a boss 193 formed integrally with the housing 0 and itsprotruding end has pinned to it a knob 194 which may be'turned to rotatethe pinion 190 which is in mesh with the toothed rack 170. To adjust thestud 174 in the slot 169in the depending leg 168 of the rocker arm R theknob 194 on the rod 17 0 the toothed rack 17 0 is raised or lowered inthe channel 179 as the case may be.

The shoe211 secured tothe'stud 202 is provided with an orifice 216 which isadapted to receive the end of the dis tributing bar or reciprocatingshaft 165, and secured therein by means of a drive fit. Thisdistributing bar-165 extends through an-aligned orifice 317 in the side5 of the housing 2 to which the distributing arm D is secured.

The cam members 60 and 61 as before described are secured respectivelyto the shaft- 64 and the sliding sleeve member 79 and as the profile orlead of the cam faces 217 and 218 of the cams 60 and 61 are the samethey mesh or match when the distributing .bar orreciprocating shaft 165is in its extreme left position as illustrated in Figs. 1 and 3. The cam61 secured to the sliding sleeve member 79 is heldin engagement with cam60 by means of a helical spring 219 around the shaft 64, one end ofwhich rests against a plate 220 resting in the bore of the bearing 66and its other end rests against the sliding member 79 on the shaft 64.The shaft 64 when rotating causes the cam 60 to rotate and the leadangle of this rotating cam 60 engages the lead angle of the cam 61supported on the sliding sleeve 79 and forces the sleeve 7 9, itssupported cam 61 and rocker arm R to the left with reference to Fig. 4,against the normal compression of spring 219 and when the sleeve 7 9 andits supported parts have reached theirlimit of travel in that directionand starts their travel in the opposite direction, the sleeve 79, andits supported parts are moved in the opposite direction under theinfluence of the compressed spring 219 with the lead angle of the cam 61following the lead angle of the rotating cam 60 on the shaft 64 whichwill be more fully hereinafter described.

Referring to Figs. 1 and 10 I show. a distributor arm I) secured to thereciprocating shaft 165. The distributor arm D comprises a split member221 secured to the reciprocating shaft-165 by means of a screw 222 whichpasses through a suitable orifice in the upper split portion of the.member 221 and has screw threaded engagement with a tapped orifice inthe lower split portion of the memher 221 to clamp the member'to thereciprocating shaft 165. The member 221 is provided with apair ofupwardly extending arms 223 and 224 which are provided with alignedorifices 225 for receiving a shaft 226 upon which an arm 221 15 secured,the said shaft 226 and its supported arm 227 being pivotally supportedin the aligned orifices .225. A block 228 resting between the arms 228is positioned between the arms 223 and 224 of the member 221 with theshaft 226 which supports the arm 227 resting in the slots 231 of thelegs 230, and the arm 227 supported on the shaft 226-in turn-resting inthe bifurcated portions 229 of the block 228. A threaded stud 232 whichis threaded through a tapped orifice 233 in the block 228 is rotatablysupported in a pair of aligned onfices 234 in the ear extensions 235 ofthe arms 223 and 224,- its one end being provid ed with a head 236 andits other end 237 being reduced to receive a knob 23.8 which is suitablypinned thereto.

- From the'above description it will beseen that the shaft 226 and itssupported arm 227 are pivotally supported by the arms223'and f 224 ofthe member 221 and the block-228 provided with the slots 231 in whichthe shaft 226 rests and the bifurcated portion 229 in which the arm-227rests in combination with the threaded stud 232 which is in a threadedengagement with the .block 228 forms adjustable means for moving the arm227 to the right or left.- lVith the parts linked together as justdescribed it is readily apparent that when the knob 238 is turned to theright with reference to Fig. 10-the the block 228 is moved .to the rightwith reference to Fig. 11. This movement of the stud 232 is also rotatedand due to thescrew connection between the threaded stud 232 and thetapped orifice 233 in the block 228 block 228 to the right caused'theshaft 226 and its supported arm 227 to also move to v the right for thereason that the arm 227 rests in the bifurcated portion 229 of the block228 and as the shaft 226 is'pivotally supported in the orifices 225 inthe arms 223 and 224 of the member 221. These orifices.

225 form bearings for the sliding shaft 226 in its limited travel to theright or left. The shaft 226 which rests in the slots 231 of the block228 forms a bearing upon which the block 228 slides and also preventstilting of the" block 228 when the stud 232 is turned to move the block228. When the knob 238 is turned to the left the block 228 is also movedto 'the left with reference to Fig. 11 andwauses the shaft 226 and itssupported arm 227 to also move to the left for reasons alreadydescribed. The movement of the block 228 ,to the right or left islimited for when it is moved to its extreme rightor left position thefaces 240 and 241 of the block 228 will engage the respective innerfaces 242 and 243 of the arms 223 and 224 of the member 221. The arm 227extends forward toward the winding spindle 3 and sup ports a pair ofball bearing guide wheels 245 and'246 for theusual purpose of guidingthe wire from the source of supply to the electromagnet spool upon whichthe wire is being wound. The arm 227 is adapted to be raised or loweredwith reference to Fig. 10,

by reason ofits being pivot-ally supported by the shaft 226 and tomaintain it in any of its adjusted up or down positions, I provide aleaf spring 247 Whichis secured to the member 221 by means of a screw248. The

free end-249. of the angular portion of" the spring 247 engages aportion of the arm 227 and the tension ofthe spring 247 is such as tofrictionally hold the arm 227 'in any of its positions. A stop 250secure'd to the member 221 limits the movement of the arm 227 in itsdownward movement.

The removable cover capv 105 is secured to the housing G by suitablescrews which Y i controlling the length of stroke of'the' reoiprocatingshaft 165, I vwill now describe the operation of the winding'machineandthe adjusting means for adjusting the length of stroke of thereciprocating shaft 165 from 1 left to right. Now when the clutch pedalof the power drive (not shown) is actuated the belt connection betweenthe source of power and the pulley 4 on the spindle shaft 3 will rotatethe spindle shaft 3; The worm 130 and the apparatus associated therewithfor on the shaft 3 meshes with the worm gear 109, causing rotation ofthe worm gear 109,

and through the agency of the] pinion" 108 on the transverse shaft 107upon which the worm gear 109 is secured. and the gear wheel 111, pinion110 supported'by' the arm 112 and the gear wheel 106 and bevel pinion101 ,on the transverse shaft 103, and the bevel gear on the shaft 64rotary motion the cam 60.- to cause rotation of the same.

extreme right position with reference to Fig. 4 and the arrow indicatedon the'cam 60 indicates the direzition of travel of-the cam 60 which"will move the reciprocating shaft 165 to the left.

As'the cam 60 rotates, the lead angle of the rotating cam 60 engages thelead angle of the cam 61 supported on the sliding sleeve member 79 andforces the sleeve 79 and its supported cam 61 androcker arm R to theleft with reference to Fig. 4, against the normal compression of thespring 219. The stud 174 WlllCll is used for adjusting. the length ofstroke of the reciprocating shaft 165 passes through the slot 'l69 inthe depending arm 168 of the rocker arm R, and is locked in its adjustedposition in the slot I show the"rcciprocating shaft 165 in its 1 10is'transmitted to the shaft 64, which carries R rocks about theistud 174and 176,in the housing C means of the locklug-knob 177 and thereforethe-rocker, arm ivots about its pivot pins 90 and 91 on the s iding mem-.ber 71 and causes the upper end of the rocker arm Rto tilt to the left.The shoes 208 and T211 supported on the block 200- resting in the upperend of the rocker arm R now slide to theleft in their respectivechannels 209 and 212. The tiltingj of the upper end of the rocker arm tothe left'is permitted, due to the fact that the studs 201 and 202 I 'ofthe block 200 which supportthe same in the. rocker arm R rest in thebifurcated ends of the rocker arm. R and permit the shoes 208 and 211supported by the block 200 to move in a horizontal plane to the left intheir respective channels 209 and 212. The bushing-181 in the slot 169in the leg 1680f the rocker arm R is slidably secured therein as beforedescribed, and as the'lower endof the leg 168 of the rocker arm R movesto the right, the bushing 181- around the locked stud 174 rotatesthereon" to permit =this movement, tothe right of the leg 163 I of the'rocker arm R. The guide rod 214 secured to the shoe 211 slides throughthe guide bearing 215 and the combination of the guide rod 214 and theblock 200 permits the free movement of the shoes 208 and 211 in therespective channels 209 and 212, and as the reciprocating shaft 165 issecured to the shoe 211 it also moves to the left. The

- movement to the left of the reciprocating of the lead -angle of .thecam 61 which is shaft continues until the-'apex'of the lead angle of therotating cam passes the apex supported on the sliding'sleeve79 on theshaft 64 and when in this position] the reciprocating shaft 165 is inits. extreme left position with reference to Fig. 4. As the shaft 64continues to rotate the lead angle of the rotating cam 60 being inengagement with the lead angle ofthe cam 61 on the sleeve 79, thesleeve-79 and its supported parts are moved in. the opposite directionunder the influence of the compressed spring 2.19 which permits the leadangle of the cam 61 to follow the lead angle of the rotating cam 60 topermit the reciprocating shaft 165 j to move to the right.

When the lead angle of the cam 60 again matches or meshes with the leadangle of the cam 61 in which positionthe apexes of the respective leadangle of the cams 60 and 61 rest in thebascs of the respective leadangles of the cams GO and 61 the reciprocating shaft 165 is in itsreciprocating shaft 165 also receives this to R, and shoes- 208 and 211movement from left to right and vice verse is transmitted to thereciprocating shaft 165, and for one hand fro movement. Through the aency of the cam 61, sliding member 79, roc er arm complete revolution ofthe cam 60, the reciprocating shaft 165 will have traveled from left toright and right to left to place two' layers of convolutions of wire onthe spool supported between thehead on'the.

spindle 3 and the tail stock T,

The length ofstroke of the reciprocating shaft 165 is adjustabl'e, andto-this end 1 provide the sliding toothed rack 170 which is in mesh withthe pinion 190.

To adjust the stroke of the reciprocating s 1 5 he locking knob 177which is in threaded engagement with the threaded end of the stud 174 isloosened to permitthe stud 174 to be moved in the slot 176 in thehousing C and the slot 169 in the leg 168 I of the rocker arm R. Withthe locking."

knob 177 loosened, the adjusting knob 194 secured to the rod 191integrally formed withthe pinion 190 in mesh with the toothed rack 170may be turned. Now to decrease the throw of the rocker arm R the knob194 turned in the direction of the arrow indicated in 'Fig. 4 and causesthe pinion 190 associated with the knob 194 and-which is in mesh withthe toothed rack 170 to move the rack 170 down.- The stud 174 is securedto the rack 170 and is therefore also'meved down and as the'bushing 181.issupported on the stud 174 it moves down in the slot 169 in the leg168 of the rocker arm R. This movement 'of the stud 174 and itssupporting bushing 181 in the slot 169 increases the distance betweenthe horizontalsiidable pivoted center of the rocker arm R and-the fixedlocking center, which in this case is the stud 174. This increase of 1distance between the pivoted centers 90 and 91 of the rocker arm Rintermediate of its ends, and the .fixed locking center or stud 174aboutwhich the bushing 181 supported thereon rocks, decreases the distancethat the upper end. of the rocker arm R tilts from left to right andvice versa and as the reciprocating shaft is secured to the shoe 211,which is associated with the tilting end I of the rocker arm, thedistances that the reciprocating shaft 165 travels from left to rightand vice versa is decreased.

From the description, it is readily apparent that the reciprocatingshaft 165 is providedwvith adjusting means for. accurately adjusting thelength of its stroke, and it is also apparent from the description thatthe axjljusting means is inicrometric in that it provides an infinitenumber of adjustable positions for the fixed locking center or stud 174to provide an infinite number of lengths of travel of the reciprocatingshaft 165.

' of coil to be wound, the locking knob .177 7 When an adjustment of thereciprocating shaft 165 is obtained for a certain length w is againtightened to clamp the studl74 in its adjusted position in the slot 176in the housing C, to maintain the adjustment.

From this it is apparent that the machine of myinvention is adaptablefor various lengths of coils, and that it is a simple matter to changethe stroke or distance of travel of the distributing bar. 165 by thissimple adjusting means without the necessity of changing; gears or.substituting cams pro- VldGdWIth diiferent pitch cam faces, 7

Spools, .such as" are illustrated. in dotted lines in-Fig. 4, upon whichthe convolutions of wire are wound, areprovided with'spool heads betweenwhich these convolutio'ns of accuracies in manufacture, the distancebe-- tween the spool heads varies slightly, and as a predeterminednumber of convolutions of wire must be placed thereon, if no provisionswere made for adjusting'the distributing bar 165 .to overcome this, it;may be readily seen that if the distance between the spool'heads was atrifle over its fixed predetermined dimensions, that there would e aslight space between the inner faces of the. spool heads and the layersof -wire on the spool, permitting these unsupported ends to loosen,whereas, if this distance is below its fixed predetermined dimension,the

first few end turns of each end of the layers would pile up and form abulge at each end of the coil which would be magnified as eachsuccessive layer isplaced thereon. With the adjustable means for givingthe distributing bar 165 an infinite-number of lengths.

" of travel from left to right, and right to left, it is readilyapparent that after thefirst layer of convolutions of wires are placedon the spool, the operator can readily observe either of thesediscrepancies, and in either case, the operator may adjust thedistributing bar 165 to increase or decrease the distance of travelfromleft to right, and

vice versa, to overcome this variance of distances between the spoolheads by the simple adjusting means which includes the knob 177 and itsassociated rack 170.

The distance between the spool heads is constant, but due tomanufacturing inaccuracies, the heads are placed at varying distancesalong the core of the spool, so that when they are clamped between thehead ofthe winding spindle andthe tail stock T, the first'layer whenwound on the. core whole, to the right or left, as the. case may willreveal this discrepancy and I provide the adjustable means associatedwith the .distributing arm 227 so that the operator by turning the knob238 the threaded stud 232 will move the block 228 and arm 227 as a be,to center the spool with relation to the v distributing and 227 so thatthe -c onvol1'1- tions will be placed thereon the full-.adistancebetweefi the ispool. heads} without a I piling-up at one end of the coreand a space 7 e-tween theend of the layer and the face of the spoolhead, as would be the case if j this. adjustment were not provided. I IFrom-the foregoingit isreadily apparent thattlier'otation of the driveshaftnot only causes the windingoffc'onvolutionsl of wire upon themagnet spoohbutfalso causes the movement of the distributor member back.

and forth, and that the'mechanism for accomplishing this result-is; veryoompactand enclosed in a casing away from dust and in ury.

If itis desired to-plalcei a difi'erent of convolutions of wire .on thespool,.-;all that is necessary to do is a," change th gearing ratiobetween the drive shaft and; the distributing member. It will be noted 3that the armf 112 is provided with a slot 1 so that difierent size gearsmay be secured. I to this arm in mesh with gears 108 and 106.

The rotation of the drivesh-aft also tran ss -1nits motion to thegearsassociatedwith .the counter mechanism thereby causing the hands ofthe counter to visualize the number of revolutions of the driving shaft.Thecounter mechanism is alien-closed in' a housing or casing, and is sosituated that the visualizing mechanism of the counter devi e isimmediately before the operator of'the winding machine. 1

As. before mentioned, the operator can, change the-distance of travel ofthe feeding mechanism while the winding machine is in operation, and theoperator can also adjust the distributing mechanism to feed further tothe right or left while the machine is in operation. i

While I have described one particular embodiment of my invention, it isto be understood that the same is not limited tothe specific disclosure,but I aim to cover all the changes and modifications that come.
